Abstract

Dithizone, as an absorbent was immobilized on activated aluminum oxide as a supporter, by impregnation to separate and enrich cadmium which was determined by hydride generation coupled atomic fluorescence spectrometry. The pH, eluting reagents of appropriate concentrations, eluting rate and interference were investigated. Under optimum experimental conditions, detection limit of 0.0060 μg/L, dynamic linearity of 0.005-10.0 μg/L and relative standard deviation of 2.23 % were obtained. The method validated by national standard certified rice materials showed a good agreement with the certified values. When applied to determination of the cadmium in rice from different origins, the method exhibited recoveries of 95.9-103 %. With environmental friendly, convenient operation, fast analysis, good accuracy and high sensitivity, the method demonstrated a great potential to be used in real samples.
